Vitamin D concentrations in study groups

Groups	16th week	21th week	Mean difference*	P value†
ND	47.5 ± 7.32	36.3 ± 7.74	− 11.20 ± 1	0.001
ND + vitamin D	54.9 ± 11.53	119 ± 26.01	64.2 ± 7.8	0.001
HFD	51.2 ± 11.16	37.7 ± 11.53	− 13.5 ± 4.25	0.01
HFD + vitamin D	53.2 ± 14.11	124 ± 39.39	70.5 ± 12.85	0.001
F values	0.792	39.272	–	–
‡ P value	0.50	0.001	–	–

Data are expressed as mean ± SD. Statistical differences between groups were assessed by one-way ANOVA followed by Tukey’s test for Post Hoc analysis. Intra group comparisons of vitamin D concentration were performed by paired t-test analysis

HFD high fat diet, ND normal diet

^† P value and ^‡ P value indicated intra group and inter group differences, respectively. ^‡The significant difference is between ND versus ND + Vit D and HFD + Vit D, ND + Vit D versus HFD and HFD versus HFD + Vit D

*Mean difference was calculated by subtracting the weight of 16th from weight of 21st weeks. P < 0.05 was considered as statistically significant. n = 20 in each group
